The Sky throughout the Year
The constellations visible in the sky for a particular observer depend upon the time of night, the time of year and the latitude of the observing site. Unless you are on the equator, then some of the constellations will be permanently below the horizon, and so never be seen, while others may never set (known as circumpolar constellations), and so be visible on any clear night.
